【摘要】：采用传统晶闸管相控电源供电的电除尘器存在能耗高、效率低等问题,文章设计了一种可以解决这些问题的电除尘器用高压脉冲电源,该电源主电路主要由移相全桥逆变电路和10组相对独立的脉冲输出单元构成。采用移相全桥ZVT-PWM软开关技术控制逆变电路前后桥臂的相位差;采用同步驱动技术驱动各脉冲输出单元,使各输出脉冲叠加后获得高压脉冲;DSP准确控制电源输出高压脉冲的电压、频率和脉宽。结果表明高压脉冲电源提高了电除尘器的除尘效率,减少了对电网的干扰和电能损耗,能满足多种电除尘的要求。
[Abstract]:The electrostatic precipitator powered by traditional thyristor phase-controlled power supply has the problems of high energy consumption and low efficiency. This paper designs a high voltage pulse power supply for electrostatic precipitator which can solve these problems. The main circuit of this power supply is mainly composed of phase-shifted full-bridge inverter circuit and 10 groups of relatively independent pulse output units. The phase shift full-bridge ZVT-PWM soft switch technology is used to control the phase difference between the front and back arms of the inverter circuit, and the synchronous drive technology is used to drive the output units of each pulse, so that the voltage of the high-voltage pulse output can be accurately controlled by the high-voltage pulse ZVT-PWM after the superposition of each output pulse. Frequency and pulse width. The results show that the high voltage pulse power supply can improve the dust removal efficiency of the electrostatic precipitator, reduce the interference to the power grid and power loss, and can meet the requirements of a variety of electrostatic precipitators.
